It is not the strongest of the species that survives, nor the
most intelligent. It is the one that is the most adaptable to
change.
- attributed to Charles Galton Darwin

We talk of our mastery of nature, which sounds very grand; but
the fact is we respectfully adapt ourselves, first, to her ways.
- Clarence Day

To wade in marshes and sea margins is the destiny of certain
bird, and they are so accurately made for this that they are
imprisoned in those places. Each animal out of its habitat would
starve. To the physician, each man, each woman, is an
amplification of one organ. A soldier, a locksmith, a
bank-clerk, and a dancer could not exchange functions. And thus
we are victims of adaptation.
- Ralph Waldo Emerson
